Sunset Provision

Sunset Provision is the generic term used throughout the Tower for any numbered clause whose operation is bounded in advance by a stated expiry. Unlike a repealed clause, a sunset provision remains on the books in full and unaltered; it ceases to govern by the passage of its own term rather than by any act of amendment. The distinction is preserved by Provision 3, which fixes the calibration of all such terms against the Standard Vigil Clock of the Ninth Spiral, and it is the subject of a standing complaint from the Theoretical Jurisprudence Guild, whose members argue that a clause valid for a fixed period is not a clause but a lease.

The Tower has issued rather more sunset provisions than it has been able to count, and the resulting surplus is itself a matter of record.

Doctrine and types

Four species are recognised in the working classifications of the Custodians of Closure. The term-bound provision expires on a stated date, as in Clause 2, which governs the decommissioning of entities whose Execution has been completed but not yet acknowledged. The event-bound provision expires upon the occurrence of a named condition, such as the closing of a floor or the return of an expedition. The recursive provision expires together with the instrument that renewed it; Ordinance of Necessity is required to carry a sunset clause of its own for precisely this reason. The fourth, the suspended provision, has never run at all: it is held in reserve pending a determination that the Cartographers' Auxiliary has twice declined to make.

Annex of Conditional Sunset, introduced by Ninth Concordance, Revision 1, permits an entity dissolved under a sunset provision to be reinstated on probation. The probationary period is not itself a sunset provision. The Corrigendum of 12 Mist-Season 41 establishes that no probation may be extended by more than one full Vigil, and that an extension beyond that figure must be entered in the register as a new instrument with a new number.

The auxiliary's return

The most cited demonstration of the doctrine's limits occurred on the eleventh floor during the winter of 39, when the Cartographers' Auxiliary was sundered under a sunset provision drafted in the same session that had appointed it. The Auxiliary had been tasked with charting the outer spiral and had drawn no more than a third of it. Its sunset term expired on the fourteenth of the month, and the next morning seven of its twelve members presented themselves at the floor's west desk and resumed work.

"An instrument may not expire an obligation it has not yet realised, and the realisation of the obligation outlives the instrument."

— Provision 204, commentary on Schedule 3

The desk ward, a certain Clerk Ovin Marchant, entered the resumption as a new undertaking rather than a continuation, and was thereafter obliged to defend the entry before three successive panels. His written grievance of 41 — twenty-two leaves, appended to the floor register and never answered — remains the fullest surviving account of the dispute. It is quoted in full in Expedited Verification Annex B7 Subclause Gamma, where it is held to illustrate that "a record may outlive the office that contested it" (Annex B7, Subclause Gamma, marginal note).

Conflicts of instrument

Sunset provisions are frequently contradicted by instruments that purport to prolong them. Provision 204 provides that non-existent material holdings are catalogued in perpetuity and are not subject to any sunset whatever, while Provision 2 requires that such holdings be stored under conditions themselves reviewed at fixed intervals. The Office of Material Paradoxes reads the two together as meaning that the holding endures while its lamination is renewed; the Office of Paradoxical Acquisitions, acting under the First Paradoxical Provision, reads them as irreconcilable and has declined to comment further since 37.

A third reading, advanced by the Guild in its 44 submission, holds that the contradiction is intentional and that the interval between the two instruments is the true subject of the provision. The Guild has not withdrawn this submission, and no officer has accepted it.

The surplus register

When Seventy-Fourth Concordance defined the end of the Fifth Librarianate's tenure and set out its sunset provisions, twelve of those provisions were found, on audit, never to have attached to any office. They had been drafted, sealed and entered, but no entity was ever named to them. The surplus was transferred in 52 to a holding register in the sub-basement, where it occupies six shelves and one drawer. The register is reviewed annually. No provision has yet been removed from it, because the review itself was constituted under a sunset provision that expired in 53 and has not been renewed.

Prospective instruments are now scrutinised under the Principle of Anticipatory Provision before sealing, and Draft Provision 881.α was returned twice for want of a named entity. Instrument Provision and Calibration requires each drafted provision to be calibrated against the Vigil Clock before entry; the calibration must be witnessed by two clerks, neither of whom may be the drafter, and the witness signature may not be entered in red ink.

Third Concordance, Annex 7, records the Administrative Sunset ritual in full and should be consulted before any provision is read aloud on the floor where it was sealed.
